This is a Villanelle, written about recent research by researchers from the University of Zurich, who found that certain moths (and females in particular) have evolved to avoid travelling towards artificial light sources. One of the most well documented consequences of anthropogenic light pollution is the fatal attraction of nocturnal insects (e.g. moths) to artificial light sources, where they can die either through direct burning, or via an increased exposure to predators.

By studying moths from rural and urban environments, the scientists found that those from urban environments have evolved to be less likely to fly towards light sources than their rural counterparts.

It is uncertain what the consequences of this reduced mobility will be, but it could lead to reduced pollination and a disruption to the food chain.
